Heat index

September's average heat index is computed to be a life-threatening hot 47°C (116.6°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
